I am interested in build systems and related topics. Are there any mailing lists, forums, or other online communities focused on build systems that you would recommend?
Maybe you'll like the CD Foundation which seems to be modeled like its brethren Cloud Native Computing Foundation (CNCF) but focuses purely on continuous delivery pipelines and related services.<p><a href="https://cd.foundation/" rel="nofollow noreferrer">https://cd.foundation/</a><p>PS: You don't want to build this stuff yourself, especially since you have stuff like ArgoCD and Tekton well capable to provide the basics ;)
What you are looking for is in the discipline of DevOps. The place to start is by reading The Phoenix Project, by Gene Kim et al. Then you’ll read the Google SRE Book and the DevOps Handbook.<p>The modern approach is called CI/CD - Continuous Integration/Continuous Deployment.
